Hi,
NSArray and NSDictionary are one shot objects. Once you've created
them, they're read-only. You need to use the "mutable" version for
adding/removing objects inside a collection. See NSMutableDictionary,
NSMutableArray etc.

Hi All,
Is there a way to remove dictionary item containing same values for
a key
from a array of dictionaries?
E.g.
NSDictionary *dict1 = [NSDictionary dictionaryWithObjectsAndKeys:@
"testVal",@"testKey",....,nil];
NSDictionary *dict2 = [NSDictionary dictionaryWithObjectsAndKeys:@
"testVal1",@"testKey",....,nil];
NSDictionary *dict3 = [NSDictionary dictionaryWithObjectsAndKeys:@
"testVal3",@"testKey",....,nil];
NSDictionary *dict4 = [NSDictionary dictionaryWithObjectsAndKeys:@
"testVal",@"testKey",....,nil];
NSArray *arrDicts = [NSArray
arrayWithObjects:dict1,dict2,dict3,dict4,nil];
In the above code I want to remove the multiple dictionaries
containing
"testVal" and maintain only one dictionary containing "testVal" in
the array
"arrDict".
